Other viewers were left stunned by the extent of Donald's deceit, with one person tweeting: "#OurFather has to be the craziest documentary I've watched in a while," while another added: "Wow. #OurFather on Netflix was a crazy and wild ride. Right up to the end. Absolutely infuriating. Wow."
A third person commented: "This #OurFather documentary is beyond crazy. I couldn't imagine finding out I had dozens of siblings who lived within a 20mi radius of me."
Viewers were sickened by the documentary
For those who have yet to see the documentary, it follows Jacoba Ballard, who, after taking an at-home fertility test, discovered that she had dozens of half-siblings whose mothers had visited Donald's clinic.
Once described as the "best infertility doctor in Indianapolis", Donald had hopeful parents-to-be come to his clinic in their droves in the hopes of receiving top treatment. Unbeknownst to them, he was using his own sperm to inseminate his patients and is thought to have fathered anywhere from 50 to 90 children between 1979 and 1986.
Our Father is available to stream on Netflix.
